Segment: 0 No-of-obs-used: 10
Vel(mm/a) Vel-sig(mm/a) RMS(mm) StdDevObsUnitWt Vel-XYZ(mm/a):
N: -7.7 1.3 3.28 1.16 -20.0
E: -22.3 1.4 1.03 0.32 10.2
U: -3.4 4.0 7.55 0.75 -8.1
Error bars are plus/minus one standard deviation
Error bars on individual observations = formal-error x scale-factor.
Currently the scale-factors are: N:3.0, E:4.0, U:3.0

Red points are positions determined using final orbits
Blue points are positions determined using preliminary orbits
Vel-stddev = sqrt(WN**2+RW**2)
where WN is a white noise contribution from propagating the error bars on the observations
and RW is a random walk contribution (= a*sqrt(timespan)/timespan where a is 0.001 m/yr**1/2)
